Claims

[Claims for Utility Model Registration] (1) A first bushing mechanism mounted on the bushing plate side, a second bushing mechanism mounted on the jig side, and a first bushing mechanism mounted on the first bushing mechanism under the action of an elastic body. The first bushing includes a general-purpose bushing that is displaceably mounted, and a dedicated bushing that is displaceably mounted on the second bushing mechanism under the action of an elastic body and has a guide member fixed thereto that contacts the workpiece. Either the mechanism or the second bushing mechanism can be displaced via a drive source, and the general-purpose part bushing and the special-purpose part bushing engage with each other, and the holes bored in the general-purpose part bushing and the dedicated part bushing engage with each other. A bushing device for a gun drill, characterized in that a hole is formed in a workpiece by inserting a gun drill into the part. (2) Utility Model Registration Scope of the Claims In the device according to claim 1, the first bushing mechanism is provided with a cylindrical portion at one end thereof, while the second bushing mechanism is provided with a hole portion, and the cylindrical portion is A bushing device for a gun drill comprising a first bushing mechanism and a second bushing mechanism that fit into a hole and engage with each other. (3) Utility model registration In the device according to claim 1, a groove of a predetermined width is carved in the dedicated part bushing, and a pin is engaged with the groove to rotate the dedicated part bushing and the second bushing mechanism. A bushing device for a gun drill that prevents it from coming off. (4) Utility Model Registration The device according to claim 1, wherein one end of the guide member is formed to correspond to the shape of the workpiece. (5) Utility Model Registration Claim 1. In the device according to claim 1, the elastic body is a gun drill bushing device comprising a coil spring.
